The pH scale allows scientists to define the acidity of a substance on a scale of ________ .

0-14

Which model states than an acid is a substance that contains hydrogen and ionizes to produce hydrogen ions?

Arrhenius Model

A conjugate acid is produced when an acid accepts a hydrogen ion.

False

A neutral solution contains more hydroxide ions than hydrogen ions.

False

Acid solutions taste bitter and basic solutions taste sour.

False

An acid anhydride is an oxide that can combine with water to form a base.

False

An acid is an ion or molecule with a lone electron pair that can donate or share.

False

An acidic solution contains more hydroxide ions than hydrogen ions.

False

An aqueous solution of acid causes red litmus paper to turn blue.

False

An aqueous solution of acids and bases cause red litmus paper to turn blue

False

Conjugate acids and bases react to form Bronsted-Lowery acids band bases.

False

In a typical reaction, if the reacting acid is strong, the base produced is strong.

False

The Arrhenius model states that acids and bases share electron pairs.

False

A single arrow in a reaction means that the reaction goes to completion.

True

Acids add flavor to many beverages and foods.

True

Acids and bases have the ability to conduct electricity.

True

In solution, strong acids and bases ionize completely, but weak acids and bases ionize only partially.

True

Substances that can act as both an acid and a base are said to be amphoteric.

True

The relative amounts of hydrogen and hydroxide ions determine whether an aqueous solution is acidic, basic, or neutral.

True

Weak acids produce fewer ions than strong acids and cannot conduct electricity as well.

True

In the Bronsted-Lowery model of acids and bases, an ________ is a hydrogen donor and a ________ is a hydrogen acceptor.

acid, base

A ________ is produced when a base accepts a hydrogen ion from an acid.

conjugate acid

The ________ of a weak acid is strong.

conjugate base

When acids react with metals, they produce ________ gas.

hydrogen

A basic solution contains more ________ ions than hydrogen.

hydroxide

An acid that can donate only one hydrogen ion is called a ________ acid

monoprotic

A solution that contains equal concentrations of hydrogen and hydroxide ions is a ________ .

neutral solution

An acid that can donate more than on hydrogen ion is called a ________ acid.

polyprotic
